that might help, but since i don't know what you have i would say maybe just look for some seat rails. it looks like the sliders would fit onto whatever car you have. just ask for measurements or something. if that doesn't work then maybe going with a whole new seat rails is the way to go. i have Nagisa Auto on my car.

I just pulled a pic of civic seat rails to show you what they look like. just scroll to see which ones will fit your car.
